Pirates or Ninjas?
Star Wars or Star Trek?
Creamy or Crunchy Peanut Butter?
These topics can be debated for hours. In fact, they have for some time. The Great Debate makes a game out of that and their 2015 expansion is on Kickstarter now.
In the game, you and your friends debate topics of great or not-so-great importance. Then you vote on which side you think is correct. Note: not necessarily "right," since the game isn't about right and wrong, but about who is more persuasive.
The campaign's a bit more than half-funded and still has 28 days to go.
